Covid: 13% of hospitalized patients have severe neurological symptoms


Covid-19 can cause many dysfunctions in the body, including the nervous system. An American study shows that 13% of patients hospitalized after being infected with the coronavirus develop serious neurological symptoms. The Medisite editorial staff takes stock of these complications.

While the majority of covid-19 patients do not show sequelae after their infection, some patients develop severe disorders. A study from Boston University School of Medicine and Boston Medical Center shows that people infected with the coronavirus can have severe neurological symptoms.

Covid-19: 4 common neurological disorders in patients

To know theincidence of neurological disorders, the US team analyzed data from patients hospitalized with SARS-CoV-2 infection enrolled in the VIRUS: COVID-19 registry. It selected adult patients treated between March 25, 2020 and March 9, 2021. “Patients were included if they had SARS-CoV-2 confirmed by a PCR test within 21 days of admission to hospital Information from the registry was used to identify people who suffered fromencephalopathy at the time of their admission”. 16,225 medical records were studied in this way.

The researchers found that about 13% of patients admitted with COVID-19 in the first year of the pandemic developed severe neurological manifestations. They point out that both men and women could be affected by these complications. However, the elderly patients were most likely to suffer.

According to the data collected, “all serious neurological manifestations were associated with increased disease severityto a greater need for interventions in intensive careto one longer length of stayat theuse of a fan and higher mortality”, specify the authors in their article published in the journal Critical Care Explorations in April 2022.

The work made it possible to detail the 4 Most Common Neurological Disorders observed in people affected by covid-19. Medisite lists them in pictures.

Encephalopathy is an inflammatory disease of the brain that can alter the structure of the brain. 10.2% of patients developed this disorder.

“Our results show that encephalopathy on admission to hospital is present in at least one in 10 patients infected with SARS-CoV-2”, specifies Anna Cervantes-Arslanian, one of the authors of the study. The analysis also showed that black patients had a higher risk of developing this complication compared to patients of other origins.

2.0% of patients had a stroke on admission or during hospitalization. Stroke patients had a 3.20 risk of needing oxygenation and a 3.23 risk of having treatment for kidney failure.

Studies have shown that patients of African-American origin were more likely to suffer from this complication compared to other patients.

1.5% of patients suffered from seizures. Research also shows that these patients were 2.78% more likely to need oxygen.

Studies have shown that patients of African-American origin were more likely to suffer from this complication compared to other patients.

0.5% of patients developed meningitis (inflammation of the meninges) or encephalitis (inflammation of the brain) on admission or during hospitalization.

These disorders were linked to a higher risk of intensive care unit (ICU) admission and fewer hospital-free, ICU-free, and ventilator-free days. On the other hand, there was no higher risk of death.
